The Atlantis airships that were used in the previous Atlantis games make a reappearance in Atlantis Evolution, at least as an icon. And one of the graphics in the game includes a picture of Atlantis' destruction with these ships flying around. So even though Atlantis Evolution is a completely new series, you are making some connection to the past Atlantis games. Are there other ways in which you make a connection to the earlier games, or is the use of the airships an isolated occurence?
